In this article (Mol Cancer Ther 2010;9:569–80), which appeared in the March 2010 issue of Molecular Cancer Therapeutics (1), the blots of EP3 and EP4 along with the blot of β-actin under Fig. 6B (related with PGE2 receptors part) were incorrectly presented.
The experiments were repeated in A549 and H1299 cell lines with and without treatment with grape seed proanthocyanidins (GSP) under identical conditions as used before. Cell lysates were subjected to Western blot analysis for the detection of the levels of PGE2 receptors (EP1, EP3, and EP4), and new data were generated to confirm and verify the levels of PGE2 receptors. The equal protein loading on the gel was verified and re-confirmed using antibody against β-actin. The data obtained re-confirm the results originally reported in the article and thus correct our errors. The authors regret this error.
